JOHN ALBERT ZEINWOLDT, OF BODAFORS, SWEDEN.

PLATFORM ROCKING-CHAIR.

SPECIFICATION forming part of Letters Patent No. 695,703, dated March18, 1902. Application filed June 14, 1901. Serial No. 64,560. (Nomodel.)

To all whom it may concern.-

Be it known that I, JOHN. ALBERT ZEIN- WOLDT, a subject of the King ofSweden and Norway, residing at Bodafors, Sandsjo, Sweden, have inventedcertain new and useful Improvements in Rocking-Chairs, of which thefollowing is a specification.

The object of the invention is to provide a rocking-chair capable ofrocking freely and naturally, but restrained from passing a certainlimit; and it consists in the construction and combinations hereinafterdescribed and claimed.

In the drawings, Figure l is a side elevation of a rocking-chair andaccessories embodying my invention. Fig. '2 is a top plan View of thestool orbase upon which the chair proper rests and rocks, and Fig. 3. isan enlarged detail illustrating certain modes of attaching flexiblemetallic bands or straps employed in connection with the said base andthe rockers of the chair.

In carrying out the invention I secure to the rockers 1 and lateral barsof the base 2 flexible bars or bands of steel or other elastic material,two such bands, 3 and 4, being applied to each rocker at opposite endsthereof and thence carried down and underneath the rocker and-securedtothe ends of the corresponding lateral bars of the base farthestremoved from the points of their attachment to said rockers. The ends ofsaid bands may be bent at right angles and formed into brads or tacks,9, as indicated in Figs. 1 and 2, to be driven into the rockers andbase, and thereby secure them, or after being bent to a right angle bepassed through holes in the parts to which they are to be secured andscrewthreaded at their extremities to receive nuts as indicated in therocker portion of said figme, and there receive nuts enteringcountersinks in said ends, where they may be con cealed by'stoppers ofwood, brass, or other suitable material.

In order to guide the chair in the rocking motion and also that itsrockers may contact directly with and rock upon the broad flat uppersurface of thelateral bars of the base instead of upon the elasticbands, said bars, as well as the rockers, are longitudinally grooved orfluted, as at 5, 6, 7, and 8, to receive the bands as the chair rocksback and forth.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

In a rocking-chair the combination with the longitudinally-channeledrockers and longitudinally-channeled lateral bars of the base, of theflexible and elastic bands attached to the opposite ends of each rockerand the reverse ends of each lateral base-bar, and arranged to closeinto said channels as the chair is rocked, so that the rockers may comeinto working contact with the surface of saidbasebars and be guided bythe interlocking of said bands with the grooves.

In witness whereof I have hereunto set my hand in presence of twowitnesses.

JOHN ALBERT ZEINWOLDT.'
